LOCATION DETERMINATION BASED ON BEACON SIGNAL
TRANSMISSION TO ENABLED DEVICES
BACKGROUND
[0001] Electronic devices, and particularly portable electronic devices,
have become
extremely powerful and useful, particularly when use of such devices is
coupled with and
takes advantage of and utilizes wireless technology, such as short-range
wireless
technology (e.g., wireless transmissions via a Bluetooth protocol), cellular
technology, and
global positioning system (GPS) technology. Indeed, one of the more prevalent
capabilities
and uses of electronic devices is to facilitate location determination of a
user or object.
Location determination technology can be used for a variety of purposes,
including, but not
limited to, general convenience purposes, tactical purposes, as well as for
personal safety
purposes.
[0002] With respect to location tracking of people and objects, such as a
car or
product, the effort needed to accurately track an object's location can be
prohibitive, in
terms of cost and time. To accomplish such tracking with conventional means, a
powerful
transmitter can be included with the object or person as well as a plurality
of receivers at
any point the object or person may travel to.
[0003] With respect to personal safety and security, such as when a user
experiences an emergency or other distressing situation, the time needed to
access a
portable electronic device having location determination capabilities, such as
a mobile
smart phone, and then access a relevant communication application available on
the
portable electronic device can represent an unacceptable delay. In some
situations the user
may be unable to initiate communication altogether, such as due to being
incapacitated or
as a result of some other limiting factor. Dedicated transmission devices that
pair and
communicate over relatively short distances with a portable electronic device
can reduce
that delay time, or enable communication automatically. However, if the paired
portable
electronic device is out of range (i.e., not near or proximate the user and
the dedicated

transmission device within a certain range) the dedicated transmission device
may not be
able to communicate with its intended receiver or recipient.

DESCRIPTION OF EMBODIMENTS
[0016] Before technology embodiments are described, it is to be understood
that
this disclosure is not limited to the particular structures, process steps, or
materials
disclosed herein, but is extended to equivalents thereof as would be
recognized by those
ordinarily skilled in the relevant arts. It should also be understood that
terminology
employed herein is used for describing particular examples or embodiments only
and is not
intended to be limiting. The same reference numerals in different drawings
represent the
same element. Numbers provided in flow charts and processes are provided for
clarity in
illustrating steps and operations and do not necessarily indicate a particular
order or
sequence.
[0017] Furthermore, the described features, structures, or characteristics
can be
combined in any suitable manner in one or more embodiments. In the following
description, numerous specific details are provided, such as examples of
layouts, distances,
network examples, etc., to convey a thorough understanding of various
technology
embodiments. One skilled in the relevant art will recognize, however, that
such detailed
embodiments do not limit the overall inventive concepts articulated herein,
but are merely
representative thereof.

[0018] As used in this written description, the singular forms "a," "an"
and "the"
include express support for plural referents unless the context clearly
dictates otherwise.
Thus, for example, reference to "an" engine includes a plurality of such
engines.
[0019] Reference throughout this specification to "an example" means that
a
particular feature, structure, or characteristic described in connection with
the example is
included in at least one invention embodiment. Thus, appearances of the
phrases "in an
example" or "in an embodiment" in various places throughout this specification
are not
necessarily all referring to the same embodiment.
[0020] As used herein, a plurality of items, structural elements,
compositional
elements, and/or materials can be presented in a common list for convenience.
However,
these lists should be construed as though each member of the list is
individually identified
as a separate and unique member. Thus, no individual member of such list
should be
construed as a de facto equivalent of any other member of the same list solely
based on
their presentation in a common group without indications to the contrary. In
addition,
various invention embodiments and examples can be referred to herein along
with
alternatives for the various components thereof. It is understood that such
embodiments,
examples, and alternatives are not to be construed as de facto equivalents of
one another,
but are to be considered as separate and autonomous representations under the
present
disclosure.
[0021] Furthermore, the described features, structures, or characteristics
can be
combined in any suitable manner in one or more embodiments. In the following
description, numerous specific details are provided, such as examples of
layouts, distances,
network examples, etc., to provide a thorough understanding of invention
embodiments.
One skilled in the relevant art will recognize, however, that the technology
can be practiced
without one or more of the specific details, or with other methods,
components, layouts, etc.
In other instances, well-known structures, materials, or operations may not be
shown or
described in detail to avoid obscuring aspects of the disclosure.
[0022] In this disclosure, "comprises," "comprising," "containing" and
"having"
and the like can have the meaning ascribed to them in U.S. Patent law and can
mean
"includes," "including," and the like, and are generally interpreted to be
open ended terms.
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
The terms "consisting of' or "consists of' are closed terms, and include only
the
components, structures, steps, or the like specifically listed in conjunction
with such terms,
as well as that which is in accordance with U.S. Patent law. "Consisting
essentially of' or
"consists essentially of' have the meaning generally ascribed to them by U.S.
Patent law.
In particular, such terms are generally closed terms, with the exception of
allowing
inclusion of additional items, materials, components, steps, or elements, that
do not
materially affect the basic and novel characteristics or function of the
item(s) used in
connection therewith. For example, trace elements present in a composition,
but not
affecting the composition's nature or characteristics would be permissible if
present under
the "consisting essentially of' language, even though not expressly recited in
a list of items
following such terminology. When using an open-ended term in this written
description,
like "comprising" or "including," it is understood that direct support should
be afforded
also to "consisting essentially of' language as well as "consisting of'
language as if stated
explicitly and vice versa.
[0023] The terms "first," "second," "third," "fourth," and the like in the
description
and in the claims, if any, are used for distinguishing between similar
elements and not
necessarily for describing a particular sequential or chronological order. It
is to be
understood that any terms so used are interchangeable under appropriate
circumstances
such that the embodiments described herein are, for example, capable of
operation in
sequences other than those illustrated or otherwise described herein.
Similarly, if a method
is described herein as comprising a series of steps, the order of such steps
as presented
herein is not necessarily the only order in which such steps can be performed,
and certain of
the stated steps can possibly be omitted and/or certain other steps not
described herein can
possibly be added to the method.
[0024] As used herein, comparative terms such as "increased," "decreased,"
"better," "worse," "higher," "lower," "enhanced," "minimized," "maximized,"
"increased,"
"reduced," and the like refer to a property of a device, component, function,
or activity that
is measurably different from other devices, components, or activities in a
surrounding or
adjacent area, in a single device or in multiple comparable devices, in a
group or class, in
multiple groups or classes, related or similar processes or functions, or as
compared to the
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
6
known state of the art. For example, a data region that has an "increased"
risk of corruption
can refer to a region of a memory device, which is more likely to have write
errors to it than
other regions in the same memory device. A number of factors can cause such
increased
risk, including location, fabrication process, number of program pulses
applied to the
region, etc.
[0025] As used herein, the term "substantially" refers to the complete or
nearly
complete extent or degree of an action, characteristic, property, state,
structure, item, or
result. For example, an object that is "substantially" enclosed would mean
that the object is
either completely enclosed or nearly completely enclosed. The exact allowable
degree of
deviation from absolute completeness can in some cases, depend on the specific
context.
However, generally speaking, the nearness of completion will be so as to have
the same
overall result as if absolute and total completion were obtained. The use of
"substantially"
is equally applicable when used in a negative connotation to refer to the
complete or near
complete lack of an action, characteristic, property, state, structure, item,
or result For
example, a composition that is "substantially free of' particles would either
completely lack
particles, or so nearly completely lack particles that the effect would be the
same as if it
completely lacked particles. In other words, a composition that is
"substantially free of' an
ingredient or element can still actually contain such item as long as there is
no measurable
effect thereof.
[0026] As used herein, the term "about" is used to provide flexibility to
a numerical
range endpoint by providing that a given value can be "a little above" or "a
little below" the
endpoint. However, it is to be understood that even when the term "about" is
used in the
present specification in connection with a specific numerical value, that
support for the
exact numerical value recited apart from the "about" terminology is also
provided.
[0027] The term "coupled," as used herein, is defined as directly or
indirectly
connected in an electrical or nonelectrical manner. "Directly coupled" items
or objects are
in physical contact and attached to one another. Objects or elements described
herein as
being "adjacent to" each other can be in physical contact with each other, in
close proximity
to each other, or in the same general region or area as each other, as
appropriate for the
context in which the phrase is used.

[0028] Numerical amounts and data can be expressed or presented herein in
a range
format. It is to be understood, that such a range format is used merely for
convenience and
brevity, and thus should be interpreted flexibly to include not only the
numerical values
explicitly recited as the limits of the range, but also to include all the
individual numerical
values or sub-ranges encompassed within that range as if each numerical value
and sub-
range is explicitly recited. As an illustration, a numerical range of "about 1
to about 5"
should be interpreted to include not only the explicitly recited values of
about 1 to about 5,
but also include individual values and sub-ranges within the indicated range.
Thus,
included in this numerical range are individual values such as 2, 3, and 4 and
sub-ranges
such as from 1-3, from 2-4, and from 3-5, etc., as well as 1, 1.5, 2, 2.3, 3,
3.8, 4, 4.6, 5, and
5.1 individually. This same principle applies to ranges reciting only one
numerical value
as a minimum or a maximum. Furthermore, such an interpretation should apply
regardless
of the breadth of the range or the characteristics being described.
[0029] As used herein, the term "circuitry" can refer to, be part of, or
include
an Application Specific Integrated Circuit (ASIC), an electronic circuit, a
processor
(shared, dedicated, or group), and/or memory (shared, dedicated, or group)
that execute one
or more software or firmware programs, a combinational logic circuit, and/or
other suitable
hardware components that provide the described functionality. In some aspects,
the
circuitry can be implemented in, or functions associated with the circuitry
can be
implemented by, one or more software or firmware modules. In some aspects,
circuitry can
include logic, at least partially operable in hardware.
[0030] Various techniques, or certain aspects or portions thereof, can
take the form
of program code (i.e., instructions) embodied in tangible media, such as
floppy diskettes,
compact disc-read-only memory (CD-ROMs), hard drives, transitory or non-
transitory
computer readable storage medium, or any other machine-readable storage medium
wherein, when the program code is loaded into and executed by a machine, such
as a
computer, the machine becomes an apparatus for practicing the various
techniques.
Circuitry can include hardware, firmware, program code, executable code,
computer
instructions, and/or software. A non-transitory computer readable storage
medium can be a
computer readable storage medium that does not include signal. In the case of
program

WO 2019/243856

code execution on programmable computers, the computing device can include a
processor,
a storage medium readable by the processor (including volatile and non-
volatile memory
and/or storage elements), at least one input device, and at least one output
device. The
volatile and non-volatile memory and/or storage elements can be a random-
access memory
(RAM), erasable programmable read only memory (EPROM), flash drive, optical
drive,
magnetic hard drive, solid state drive, or other medium for storing electronic
data. The
node and wireless device can also include a transceiver module (i.e.,
transceiver), a counter
module (i.e., counter), a processing module (i.e., processor), and/or a clock
module (i.e.,
clock) or timer module (i.e., timer). One or more programs that can implement
or utilize
the various techniques described herein can use an application programming
interface
(API), reusable controls, and the like. Such programs can be implemented in a
high level
procedural or object oriented programming language to communicate with a
computer
system. However, the program(s) can be implemented in assembly or machine
language, if
desired. In any case, the language can be a compiled or interpreted language,
and combined
with hardware implementations.
100311 As used herein, the term "processor" can include general purpose
processors,
specialized processors such as central processing units (CPUs), graphics
processing units
(GPUs), digital signal processors (DSPs), microcontrollers (MCUs), embedded
controller
(ECs), field programmable gate arrays (FPGAs), or other types of specialized
processors, as
well as base band processors used in transceivers to send, receive, and
process wireless
communications.
[0032] It should be noted that when a plurality of similar objects are
depicted (e.g.,
FIG.1 shows three portable electronic devices (114A to 114C) and a two low
energy
electronic devices (120A and 120B)), the base number for that object may be
used to refer
to a general version of that object. Thus, if 120 is used to refer to a low
energy electronic
device it should be understood to be referring to low energy electronic
devices generally,
and not to a particular depicted object.

[0033] An initial overview of technology embodiments is provided below and
then
specific technology embodiments are described in further detail later. This
initial summary
is intended to aid readers in understanding the technology more quickly but is
not intended
to identify key features or essential features of the technology nor is it
intended to limit the
scope of the claimed subject matter.
[0034] Aspects of the present technology are directed toward enabling a
low energy
electronic device to reliably communicate with a plurality of other devices.
In some
examples, the low energy electronic device can comprise a portable, self-
contained (i.e.,
having a housing with the components, including a power supply, supported
therein) low
energy electronic device that can be carried by a user and used in emergency
or other
distressful situations, and that can comprise a housing in support of a
transceiver, a user
interface or input operable to initiate a user input or user input signal, a
power supply, and a
processing unit operable with the user interface and the transceiver to
control the
transceiver. The user interface can comprise an electromechanical user
interface (e.g., a
button), an electronic user interface (e.g., a touch screen), a biometric user
interface, and
others as will be apparent to those skilled in the art. In some examples, when
a user
activates the low energy electronic device via the user interface or input,
the processing unit
sets or switches the transceiver into a one-way communication mode and begins
transmitting signals.
100351 In some examples, a low energy electronic device is a device that
has a
power consumption less than 0.5 Watts and a peak current consumption of less
than 15
milliamps (mA). In some examples, the average current consumption of a low
energy
electronic device is less than 500 micro amps ( A).
[0036] In some examples, the one-way communication mode transmits a
generic
wake-up signal for a first period of time, which can be any desired duration
of time (e.g.,
between 1 and 5 seconds, or others). The one-way communication mode can use a
communication protocol based on a Beacon communication protocol. One prior
Beacon
communication protocol typically involves broadcasting a unique identifier for
the device
as well as two supplemental values (called the major and minor values).
However, the
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
present technology utilizes a beacon communication protocol different from
those in the
prior art, and that is customized to the specific needs of the present
technology.
[0037] In one example, all low energy electronic devices that implement
this unique
beacon communication protocol can have the same source identifier (which can
comprise a
16 byte value that is also called a universal unique identifier (UUID)). Thus,
to a receiver,
each low energy electronic device has and transmits to the receiver the same
source
identifier. In addition, the supplemental values have been increased (e.g., to
16 bytes each)
and can be used to transmit additional information. For example, a generic
wake-up signal
includes a source identifier instead of a UUID and a generic wake-up
identifier (a 32 byte
value) instead of the major and minor values.
[0038] The generic wake-up signal allows the current technology to solve
various
problems associated with currently existing solutions. Specifically, existing
solutions
require a paired device (e.g., an electronic device capable to communicate
long distances
over network) to ensure that a personal low energy electronic device can
connect to a server
system. As a result, when the personal low energy electronic device is
separated from the
paired electronic device, the personal low energy electronic device is unable
to
communicate with the remote server, effectively rendering it inoperable.
[0039] The present technology overcomes this problem as described above,
by
allowing each low energy electronic device to connect to any portable
electronic device that
has the associated application installed thereon by enabling a generic wake-up
signal.
Thus, all users who have the application installed act as a network, each
allowing the others
to send messages through their respective portable electronic devices. This
solution has the
advantage of enabling much greater utility for each low energy electronic
device without
the additional cost of purchasing or otherwise enabling multiple portable
electronic devices.
[0040] In some examples, the communication protocol can comprise a low
energy
proximity sensing protocol that can enable portable electronic devices (e.g.,
mobile phones,
tablets, and others) within a close range (e.g., within 70 meters, but this is
certainly not
intended to be limiting in any way) to receive the transmissions. Thus, when
the generic
wake-up signal is transmitted, any portable electronic device within range can
receive the
signal.
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
11
[0041] Any such portable electronic device that has an installed
application
associated with the low energy electronic device can be configured, such that
whenever it
receives a communication that includes both the source identifier associated
with the low
energy electronic device and the generic wake-up signal, it will cause the
associated
application to be activated in one or more ways. Thus, the low energy
electronic device is
not limited only to communicating with a paired portable electronic device,
such as a
specific smartphone of the same user in possession of the low energy
electronic device.
Instead, it can communicate with any portable electronic device within range
that has the
associated application installed. In this way, a user with a low energy
electronic device can
still send messages even if the actual paired portable electronic device
(e.g., the user's own
mobile phone) is out of range.
[0042] In some examples, when a portable electronic device, with the
application
installed, receives the generic wake-up signal, the portable electronic device
recognizes the
source identifier value (which is common to all person emergency devices that
implement
the herein disclosed protocol) as well as the generic wake-up identifier in
the supplemental
values. In response, the receiving portable electronic device (or any
electronic device with
the application installed and the ability to receive the signal) will activate
the application
even if the application was in an off or inactive or dormant state.
[0043] Once the associated application on a particular portable electronic
device has
been activated, the application will monitor for future communications from
the low energy
electronic device. After the first time period, the processing unit (e.g., a
signal controller)
of the low energy electronic device stops directing the transceiver to
transmit the generic
wake-up identifier and directs the transceiver to begin transmitting a user
identifier signal.
The user identifier signal includes the source identifier, which is
transmitted with every
outgoing signal from the low energy electronic device, and a user identifier
associated with
the specific low energy electronic device transmitting the signal. The user
identifier is a
value associated with the specific low energy electronic device and can be pre-
established,
such as with a server system, when the user is setting up the low energy
electronic device.
Like the generic wake-up identifier, the user identifier can be a 32 byte
value.

WO 2019/243856
PCT/1B2018/000823
12
[0044] The portable electronic device can store one or more user
identifiers. A user
identifier is stored at the portable electronic device when the low energy
electronic device is
registered or otherwise set-up. Once a portable electronic device registers a
user identifier
associated with a low energy electronic device, the portable electronic device
and the low
energy electronic device are considered paired. In general, users pair a low
energy
electronic device they own with a portable electronic device that they also
own.
[0045] When the portable electronic device receives the user identifier
signal
(including the user identifier) from the low energy electronic device, the
portable electronic
device compares the received user identifier with one or more stored user
identifiers. If the
received user identifier matches a stored user identifier, the low energy
electronic device
from which the user identifier is received is determined to be paired with the
receiving
portable electronic device.
[0046] When the portable electronic device determines that the low energy
electronic device is paired with the portable electronic device, the portable
electronic device
can perform a foreground function. A foreground function can comprise an
action taken by
the portable electronic device from an activated feature on the portable
electronic device,
and that is or becomes a primary function of the portable electronic device,
which function
or action can be perceptible and conspicuous. In contrast, a background
function is a
function that takes place in the background of a portable electronic device
and is
inconspicuous and largely unnoticeable.
[0047] In one example, a foreground function can comprise activating the
camera or
the microphone, or both, of the portable electronic device to record visual or
audio data, or
both, in the area of and nearby the portable electronic device for a
predetermined time
period. Other foreground functions are contemplated, as discussed herein. The
portable
electronic device can send the recorded visual and/or audio data as well as
the user
identifier and the location of the portable electronic device to a server
system. This can
occur via wireless communication with the server, such as via a cellular
network. The
predetermined time period can be any desired time period. For example, the
time period
can be less than one minute, more than one minute, can include different
intervals or
periods, or any other period of time or sequence of times.

[0048] Initiating a foreground function on the paired portable electronic
device,
such as recording visual and/or audio data from the camera and/or microphone
of the
portable electronic device, solves various problems associated with existing
technologies.
Specifically, current systems that notify users when a particular user has
activated their low
energy electronic device send very little information that would be of use to
the receiving
users, or that could be of a benefit to or assist the notifying user. This
lack of information
makes it difficult for receiving users to respond to a situation correctly.
[0049] Unlike current systems, with the present technology, the paired
portable
electronic device, through or via the installed application, sends the current
location of the
paired portable electronic device to the server system, as well as collects
visual and audio
data, such as of the user, at and near the portable electronic device. Being
able to see and
hear a situation that may have caused a user to activate a low energy
electronic device
provides significantly more information to the receiving user(s), allowing
them to correctly
respond, such as to what may be an emergency or distressing situation. This
has clear
advantages over other prior systems and methods, including those that only
send text based
messages in the event of an emergency. Existing solutions either relay very
little
information, take additional time to activate, or both. The technology
disclosed herein has
the advantage of being very quick to activate and providing as much
information as
possible.
[0050] In some examples, the server system determines, based on the user
identifier,
a pre-established group of users associated with the user identifier. For
example, a user can
connect his or her profile to the profiles of the user's family members or
friends or any
other individual or group of individuals. These people are then associated
with or
otherwise linked to the user identifier at the server system. In some
examples, the server
system transmits the location of the user's portable electronic device and any
recorded
audio or video data to the pre-established group of linked users. In other
examples, the
server system transmits an estimated location of the low energy electronic
device to the pre-
established group of users associated with the user identifier.
[0051] Using the locations of multiple portable electronic devices to
estimate a
location of a low energy electronic device solves a significant problem with

require a user's location. Specifically, if a low energy electronic device
does not know its
own location, the location of a connected device can be used as an approximate
location.
However, depending on the specific range of the low energy electronic device,
the possible
area in which the low energy electronic device may be found is likely still
quite large. In
contrast, the present technology allows the location of the low energy
electronic device to
be estimated with more accuracy by relying on more than one portable
electronic device for
a potential location. This has the advantage of increasing accuracy without
the additional
cost of the user purchasing additional portable electronic devices or similar
devices.
[0052] FIG. 1 illustrates an example server-client system 100 for enabling
a low
energy electronic device, such as a personal emergency (or other distressing
situation)
device (e.g., a panic button/device, a medical alert device, or others), in
accordance with an
example embodiment. In some examples, the server-client system 100 can include
one or
more low energy electronic device (e.g., see low energy electronic devices
120A and 120B,
each of which comprise the same similar components and function), one or more
portable
electronic devices 114A ¨ 114C having an application 116A ¨ 116C stored
thereon and
associated with the low energy electronic devices 120A and 120B, and a server
system 102.
In some examples, the low energy electronic device(s) can connect to the one
or more
portable electronic devices via a short-range wireless connection, such as a
Blue Tooth
connection. One or more communication networks 110 interconnect the portable
electronic
devices (116A to 116C) and the server system 102. The communication networks
110 can
be any of a variety of network types, including local area networks (LANs),
wide area
networks (WANs), wireless networks, wired networks, the Internet, personal
area networks
(PANs), or a combination of such networks, or others as will be apparent to
those skilled in
the art.
[0053] In some examples, the low energy electronic device 120A can include
a
transceiver 122, a processor or signal controller 124, user interface or input
126, identifier
storage 128. In some examples, the transceiver 122 is capable of transmitting
in both a one-
way mode and a two-way mode. In some examples, the signal controller 124 has
logic
and/or circuitry that controls the transmission mode and the content being
transmitted. For
example, in one-way mode, the signal controller 124 can use a communication
protocol
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
based on a beacon communication protocol to broadcast information. In
addition, the low
energy electronic device 120A can include a power source, such as a battery
and any
components needed to utilize the battery that is not pictured. In some
examples, the low
energy electronic device 120 can enable and disable the transceiver 122 for
small amounts
to time to preserve battery life.
[0054] One traditional Beacon communication protocol involves broadcasting
a
unique device identifier (UUID) for a beacon device, or a group of beacon
devices with a
common owner, (e.g., a 16 byte string) and two supplemental values. The
supplemental
values are a major value (e.g., a two byte string generally used to
distinguish a smaller
subset of beacon devices within a larger group) and a minor value (e.g., a two
byte
identifier used to identify individual beacon devices).
[0055] Unlike the traditional Beacon protocol, the Beacon protocol
discussed herein
has been modified or customized to better fit the needs of the disclosed
system. The
plurality of low energy electronic devices 120A and 120B (although any number
of low
energy electronic devices are contemplated) implementing the Beacon protocol
discussed
herein can comprise the same source identifier. In other words, the device
identifier across
the plurality of low energy electronic devices 120A and 120B is not unique to
each of the
plurality of low energy electronic devices 120A and 120B. With this Beacon
protocol, the
supplemental values (the major and the minor values) are lengthened to 16
bytes each (for a
total of 32 bytes). Certain values in the 32 byte range can be assigned as a
user identifier to
identify respective particular low energy electronic devices, as discussed in
more detail
below. In addition, one value in the 32 byte range can be established as a
generic wake-up
identifier that all portable electronic devices having the application
installed can receive and
recognize and respond to.
[0056] In some examples, the user interface or input 126 allows a user to
interact
with the low energy electronic device 120A to initiate a user input signal to
the signal
controller 124. For example, the user interface or input 126 could be one of
an
electromechanical user interface (e.g., a button), an electronic user
interface (e.g., a touch
screen, a microphone), a biometric user interface, and any others as will be
recognized by
those skilled in the art. A user can interact with the user input to initiate
the user input
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
16
signal to cause the low energy electronic device 120A to activate. For
example, if the low
energy electronic device comprises a personal and portable low energy
electronic device
(e.g., a panic button for use in emergency or other distressful situations)
and the user input
126 comprises a button, the user can activate the low energy electronic device
120A by
pressing the button, which generates the user input signal to be sent to the
signal controller
124.
[0057] In response to activation of the low energy electronic device 120
by the user,
the signal controller 124 places or switches the transceiver 122 into a one-
way
communication mode (e.g., from an off mode or sleep mode). In the one-way
communication mode, the transceiver 122 transmits what can be termed a generic
wake-up
signal for a first time period. As noted above, the generic wake-up signal
includes the
source identifier (16 bytes) and a generic wake-up identifier (32 bytes from
the major and
minor values). Unlike conventional low energy electronic devices, each low
energy
electronic device of the present disclosure is configured to activate an
application in
response to the same generic wake-up identifier. As a result, any low energy
electronic
device (e.g., either low energy electronic device 120A or low energy
electronic device
120B, or both) can wake up any portable electronic device (e.g., portable
electronic devices
114A, 114B, or 114C, or any combination of these) that has the associated
application
installed, and that is within range of the low energy electronic device(s) to
receive the
generic wake-up signal with the generic wake-up identifier.
[0058] In some examples, a portable electronic device 114 uses a radio
receiver to
receive a variety of signals. A portable electronic device 114 can analyze
some or all of the
signals it detects. The portable electronic device 114, with the application
116 installed,
can recognize the generic wake-up signal from one or more low energy
electronic devices.
In response, the portable electronic device 114 can activate the associated
application 116
in one or more ways. In some examples, the application 116 is activated
without otherwise
activating the portable electronic device 114, such as in the background.
[0059] For example, a smartphone detecting the generic wake-up signal can
activate
the application to perform a passive or background function, but the
application will not
cause the portable electronic device to perform any active or foreground
functions, such as
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
17
to turn on its screen or unlock the device, or perform any other foreground
functions.
Instead, the application passively performs its processes in the background
without other
indications that the application 116 is running. In other examples,
particularly in the case
where the portable electronic device is paired to the specific low energy
electronic device
whose generic wake-up signal is being received, the application can cause the
portable
electronic device to activate and perform other more active foreground
functions, as
discussed herein.
[0060] A single low energy electronic device (e.g., low energy electronic
device
120A) can send a signal that is received by the plurality of portable
electronic devices 114A
¨ 114C. In addition, each low energy electronic device 120A and 120 B can be
paired with
a respective particular portable electronic device (e.g., the phone of the
user of the low
energy electronic devices 120). For example, low energy electronic device 120A
can be
paired with portable electronic device 114A, which can comprise a smartphone
of the user
of the low energy electronic device 120A, and low energy electronic device
120B can be
paired with portable electronic device 114B, which can comprise the smartphone
of the user
of the low energy electronic device 120B.
[0061] Although each low energy electronic device 120 is paired with one
or more
specific portable electronic devices 114, each of the low energy electronic
devices 120A
and 120B are operable to wake up any portable electronic device (e.g.,
portable electronic
devices 114A, 114B, or 114C) within range and that has the associated
application installed
thereon due to the fact that the generic wake-up identifier is the same for
low energy
electronic devices 120A and 120B (or any others using the technology discussed
herein). It
is noted that although only two low energy electronic devices are shown in
FIG. 1, any
number of low energy electronic devices are contemplated, each of which will
have the
same generic wake-up identifier. Indeed, any low energy electronic device
configured in
accordance with the teachings as disclosed herein can be used to send a
generic wake-up
signal, each of which will comprise the same generic wake-up identifier, to
any number of
portable electronic devices within range and that have installed thereon the
associated
application to cause the portable electronic devices to activate in one or
more ways, the
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
18
specific way in which the portable electronic device is activated depending
upon the
particular low energy electronic device whose signal is being received.
[0062] In some examples, once the first time period has elapsed, the
signal
controller 124 changes the outgoing signal from the generic wake-up signal to
a user
identifier signal to be transmitted by the transceiver 122. The user
identifier signal includes
the source identifier and a user identifier. As noted above, the user
identifier can be a 32
byte value unique associated with the transmitting low energy electronic
device 120. In
some examples, the signal controller 124 continues to direct the transceiver
122 to transmit
the user identifier signal for a second time period. The user identifier
signal is receivable
by any portable electronic device within range.
[0063] In some examples, setting up a low energy electronic device 120A
(e.g.,
initializing the device and/or or registering it with the sever system 102)
includes pairing
the low energy electronic device 120A with a specific portable electronic
device (e.g.,
portable electronic device 114A) and registering the low energy electronic
device 120A
with the server system 102. As part of a low energy electronic device 120
registration
process, the low energy electronic device 120 can transmit a device
registration request to
the server system 102 via a particular portable electronic device 114. In some
examples,
portable electronic device 114 stores a user identifier for the low energy
electronic device.
[0064] In some examples, the server system 102 generates a user identifier
during
the registration process. In other examples, the user identifier and a device
identifier of the
paired portable electronic device are stored by the server system 102, but the
user identifier
originated in the low energy electronic device 120A (e.g., as part of
preparing the low
energy electronic device for sale)). In some examples, the low energy
electronic device
120A stores the source identifier, the generic wake identifier, and the user
identifier in the
identifier storage 128. It is noted that this same process can be carried out
to initialize and
register the low energy electronic device 120B, or any others, with a specific
portable
electronic device.
[0065] Once the second time period has elapsed, the signal controller 124
can
switch the transceiver 122 into a two-way communication mode. In some
examples, this
two way communication mode can comprise a close proximity or short-range type
of
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
19
protocol, such as a Bluetooth communication protocol. In this mode, the
transceiver 122
can receive a confirmation signal from one or more of the portable electronic
devices 114A,
114B, and 114C. As discussed below, a confirmation signal may notify the low
energy
electronic device 120A that the user identifier has been received and
transferred to the
server system 102. In response to receiving a confirmation signal, the low
energy
electronic device 120A can switch into sleep mode and preserve battery life
until activated
again.
[0066] In some examples, one or more of the portable electronic devices
114A,
114B, 114C receive the user identifier from the low energy electronic devices
120. Each
respective portable electronic devices that receives the user identifier then
determines
whether the user identifier is from a low energy electronic device that is
paired with the
respective portable electronic device. This determination is made, as noted
above, based on
comparing the received user identifier with one or more user identifiers
stored at the
portable electronic device 114 (e.g., in the application 116). A user
identifier can be stored
at the portable electronic device 114 during registration of a low energy
electronic device
120.
[0067] In accordance with a determination by the portable electronic
device 114
that the low energy electronic device is paired with (or matches) the portable
electronic
device 114, the portable electronic device 114 activates a foreground
function, such as
activating the camera and/or microphone, and a record function to capture
these. The
camera and/or microphone capture local video and audio data for a
predetermined amount
of time. In some examples, the predetermined amount of time is 20 seconds, but
can be any
as described above. In some examples, a user may specify a particular
predetermined
amount of time.
[0068] Once the camera and microphone have been activated, the portable
electronic device 114 can determine the order and timing at which the data is
transmitted to
the server system 102. This determination can be made based on user
preferences or in
accordance with pre-established data handing policies. In some examples, the
portable
electronic device waits until the camera and microphone are done recording and
then
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
transfers the recorded audio and visual data at the same time as the user
identifier, device
identifier, and the location of the portable electronic device 114.
In other examples, the portable electronic device 114 transmits the user
identifier, device
identifier, and the location of the portable electronic device 114 to the
server system 102
first and then transfers the recorded audio and visual data when the portable
electronic
device 114 finishes recording them. In yet other examples, the portable
electronic device
114 sends the user identifier, device identifier, and the location of the
portable electronic
device 114 initially and then streams the audio and visual data as it is
recorded. The
portable electronic device 114 can use a communication network 110 to transfer
the audio
and visual data, user identifier, device identifier, and the location of the
portable electronic
device 114 to the server system 102.
[0069] In accordance with a determination by the portable electronic
device 114
that the low energy electronic device is not paired with the portable
electronic device 114,
no foreground function on the portable electronic device is activated (e.g.,
the portable
electronic device 114 does not activate the camera and/or microphone). In this
way, a
portable electronic device will not perform a foreground function for any low
energy
electronic device 120 except for those that are paired with the portable
electronic device
114.
[0070] In some examples, the portable electronic device can comprise a
location
determination module or system operable to determine a location of the
portable electronic
device. In one example, the location determination module can comprise a GPS
enabled
device or system. Other systems and methods include control plane locating, in
which the
portable electronic device allows a service provider to get its location based
on the radio
signal delay of the closest cell-phone towers (for situations in which the GPS
signal is not
available or the GPS service has been turned off). In addition, the portable
electronic
device may use crowdsourced Wi-Fi data can to identify a portable electronic
device's
location. These methods have the advantage of performing well in indoor
environments. In
other examples, a portable electronic device may use a combination of these
techniques to
identifier its location. There are a number of additional methods that can
enable location
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
21
based services that the portable electronic device can use to determine its
location that will
be apparent to those skilled in the art.
[0071] A plurality of different portable electronic devices (114A ¨ 114C)
can
receive the user identifier and, in response, transmit their respective
locations to the server
system 120. Thus, the server system 102 can receive the user identifier from
one or more
portable electronic devices 114 and the respective location of each portable
electronic
device 114.
[0072] The server system 102 includes a signal processing engine 104. The
signal
processing engine 104 can receive data from one or more respective portable
electronic
devices 114A to 114C. In some examples, the received data can include, but is
not limited
to, a user identifier, a location of a respective portable electronic device
114A to 114C, a
device identifier for a respective portable electronic device, an indicator of
whether the
respective portable electronic device is paired with the low energy electronic
device 120
associated with the user identifier, audio data recorded by a respective
portable electronic
device, and visual data recorded by a respective portable electronic device.
[0073] The signal processing engine 104 can determine whether to transmit
any or
all of the received data to one or more other users (e.g., devices associated
with the other
users). In some examples, this determination can be made at the server system
by
determining which users are listed in a user profile associated with the user
identifier as
being grouped with the user profile.
[0074] In some examples, the signal processing engine 104 determines which
data
to transmit to the list of users based on the received indication of whether
the sending
portable electronic device 114 is paired with the user identifier. In
accordance with a
determination that the sending portable electronic device 114 is paired with
the user
identifier, the signal processing engine 104 can send the location of the
sending portable
electronic device 114 and any recorded audio or visual or other data, such as
to those users
that are in a group. In accordance with a determination that the sending
portable electronic
device 114 is not paired with the user identifier, the signal processing
engine 104 can send
an estimated location of the low energy electronic device 120. The process for
estimating a
location of a low energy electronic device 120 is explained in more detail
below.

[0075] FIG. 2 is a flow diagram illustrating communication between a low
energy
electronic device 120 and a portable electronic device 114, in accordance one
example. In
this example, the communication between a single low energy electronic device
120 (as
shown in FIG. 1) and a single portable electronic device 114 is shown. With
reference to
FIGS. 1 and 2, the low energy electronic device 120 transmits a message in one-
way
communication or message mode 140. In some examples, the low energy electronic
device
120 sends a generic wake-up signal 150 to the portable electronic device 114.
A generic
wake-up signal 150 includes a source identifier and a generic wake-up
identifier. As noted
above, the source identifier is a 16 byte value which is send by all low
energy electronic
devices 120 associated with the disclosed technology. The generic wake-up
identifier can
be a 32 byte value pre-established to activate an associated application on
each portable
electronic device 114 that has the application installed.
[0076] The low energy electronic device 120 continues broadcasting the
generic
wake-up signal 150 for a first time period 160. Once the first time period 160
has elapsed,
the low energy electronic device 120 switches the transmitted message from the
generic
wake-up signal 150 to the user identifier signal 152. The user identifier
signal includes the
source identifier and a user identifier, which can be a 32 byte value that
identifies a
particular low energy electronic device 120 and which can also be associated
with a
particular user.
[0077] In some examples, the low energy electronic device 120 continues
transmitting the user identifier signal 152 during a second time period 162.
Once the
second time period 162 has elapsed, the low energy electronic device 120
changes into a
two-way communication or messaging mode 142 for a third time period 142. In
the two-
way communication mode 408, the low energy electronic device 120 can receive a
confirmation signal 158 from the portable electronic device 114 upon
successful receipt of
the user identifier 152.
[0078] When the low energy electronic device 114 receives a confirmation
signal
158 from a portable electronic device 114, the low energy electronic device
120 can switch
into "sleep mode" or other dormant state. This ability to quickly return to a
dormant state
allows the low energy electronic device 114 to consume far less power than
traditional
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
23
near-field communication techniques. In some examples, the cycle number 154
represents
the number of times the low energy electronic device 120 has completed the
three time
periods and transmitted their associated signals.
[0079] In some examples, the low energy electronic device 120 can, in
response to
user input or failure to receive confirmation, enter a repeat broadcast mode.
After the third
time period has elapsed, the low energy electronic device 120 can be
configured to return to
broadcasting the generic wake-up signal and restarting the three time periods,
and cycling
through these. Repeatedly broadcasting the signals may be useful in cases
where the low
energy electronic device 120 has not received a confirmation from a portable
electronic
device 114.
[0080] The low energy electronic device 120 can allow the user to provide
input as
to whether a repeating broadcast is desirable. For example, the low energy
electronic
device may have two pre-established user input types. A first user input type
instructs the
low energy electronic device 120 to complete the three time periods (one
cycle) once, as
discussed herein. Thus, the low energy electronic device 120 will broadcast
the generic
wake-up signal, the user identifier signal, and then wait for confirmation in
two-way
confirmation mode. This first user input may conserve battery life and prevent
too many
portable electronic devices from receiving the signal. A first input type can
be a single
button push. However, any other user input can serve as the first input type.
[0081] A second user input type can instruct the low energy electronic
device to
continue broadcasting the signals in the three time periods in a repeating
loop (continuous
or repeating cycles). This can be referred to as a repeat broadcast mode. In
this example,
the low energy electronic device 120 broadcasts the generic wake-up signal for
the first
time period, and then the user identifier signal for the second time period.
The low energy
electronic device 120 switches into the two-way communication mode for the
third time
period. Once the third time period has elapsed the low energy electronic
device 120 restarts
transmitting the generic wake-up identifier, and the cycle repeats. In this
way a user who
wants to ensure that it reaches as many different portable electronic devices
114 as possible
can cause the low energy electronic device 120 to initiate the second user
input type to
repeat the transmissions continuously. In some examples, the second user input
type can be
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
24
initiated by the user in accordance with the type of low energy electronic
device. In one
example, with the low energy electronic device comprising a portable, self-
contained
device, the user can initiate the second user input by pressing an input
button several times
(e.g., three times) in quick succession, which switches the low energy
electronic device into
the repeat broadcast mode, such as for emergency or panic purposes. Upon
entering the
repeat broadcast mode, the low energy electronic device can signal the user
that the repeat
broadcast mode has been initiated. For example, the low energy electronic
device can
comprise a haptic feedback device (e.g., a vibration or other similar haptic
device) that the
processor causes to be initiated in response to receiving the second user
input type (i.e., the
low energy electronic device can vibrate for a pre-determined period of time,
or for a
specific number of times (e.g., three times)). This can confirm to the user
that the low
energy electronic device is in the repeat broadcast mode. In some examples,
each time the
low energy electronic device 120 completes a cycle, a cycle number 154 is
transmitted to
the portable electronic device 114 indicating how many cycles have been
completed.
[0082] When a low energy electronic device 120 is in the repeat broadcast
mode,
the server system 102 can track the location of the low energy electronic
device 120 over
time by transmitting the repeated signals for the respective time periods to
multiple portable
electronic devices equipped with the associated application. Thus, the
multiple detected
locations and the resulting generated path of a user or an object with the low
energy
electronic device can be stored on the server system 102 based on each
location sent in by a
portable electronic device 114 that has the associated user identifier. In
some examples, the
server system 102 can predict a future path and potential locations for a low
energy
electronic device 120 based on past locations.
[0083] Furthermore, when the low energy electronic device 120 is in repeat
broadcast modem, the low energy electronic device 120 can transmit the generic
wake-up
signal and the user identifier signal to a plurality of portable electronic
devices 114. Each
time a respective portable electronic device 114 receives these signals, the
respective
portable electronic device 114 will respond with a confirmation signal 158,
notifying the
low energy electronic device 120 that the signals have been received and the
user identifier
has been sent to the server system 102 (along with the location of the
respective portable
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
electronic device 114). Upon receipt of the confirmation signal 158 from a non-
paired
portable electronic device 114, the low energy electronic device 120 signals
the user that a
portable electronic device 114 has transmitted the user identifier and the
location of the
portable electronic device 114 to the server system 102. For example, the low
energy
electronic device can initiate the haptic feedback device to vibrate for a pre-
determined
period of time or for a specific number of times (e.g., vibrate one time) to
notify the user
that a portable electronic device 114 has received the signals as transmitted
the user
identifier to the server system 102. In this way, a user can know if and when
the low
energy electronic device 120 in repeat broadcast mode connects to a portable
electronic
device 114. In an emergency situation, being alerted that the low energy
electronic device
120 had connected to a portable electronic device, and thus, that an emergency
signal had
been sent to the server system 102 can allow a user to appropriate react to
this information.
[0084] The repeat broadcast mode can be operated until further user input
(e.g.,
pressing the button) causes the repetition to cease or the low energy
electronic device 120
runs out of power. In some examples, the low energy electronic device 120 can
broadcast
on repeat for up to five days or more, depending upon the power source. In
another
example, the repeat broadcast mode can be terminated in the event the paired
portable
electronic device receives the repeating signals. In this case, the paired
portable electronic
device can be operated to send a confirmation signal to the low energy
electronic device
120. Upon receipt of the confirmation signal, the low energy electronic device
120
switches to the dormant or sleep mode, and also signals the user that the
broadcast repeat
mode has been terminated. For example, the low energy electronic device can
initiate the
haptic feedback device to vibrate for a pre-determined period of time or for a
specific
number of times (e.g., vibrate two times) to notify the user that the low
energy electronic
device 120 is out of the repeat broadcast mode.
[0085] FIG. 3 is a block diagram further illustrating a server-client
system, in
accordance with some example embodiments. In some examples, the server client
system
300 includes a server system 102, a portable electronic device 114, and a
communication
network 110 to connect the server system 102 and the portable electronic
device 114. The
server system 102 can include a signal receiver 310, a signal processing unit
104, a profile

WO 2019/243856
PCT/1B2018/000823
26
matching module 314, a group manager 316, a location estimation module 114, a
media
transmission module 322, and a message module 324. In some examples, the
server system
102 can include a user profile database 330 and associated group data 332.
[0086] In some examples, the portable electronic device 114 includes an
application
116, a camera 204, and a microphone 206. The portable electronic device 114
receives a
generic wake-up signal having a generic wake-up identifier from a low energy
electronic
device, as discussed above, and as shown in FIG. 1. In response, the personal
portable
electronic device 114 activates the application 116. Once activated, the
application 116
receives the user identifier from the low energy electronic device, as this is
also transmitted
with the generic wake-up signal. Upon receipt, the portable electronic device
114 transmits
the user identifier and a location of the portable electronic device 114 to
the server system
102.
[0087] In some examples, such as in the case where the user identifier
matches a
stored user identifier at the portable electronic device 114, the application
116 can activate
one or more components of the portable electronic device 114, such as to
activate the
camera 304, microphone 306, or both for the purpose of recording audio data,
visual data,
or both. The application 116 transmits the recorded audio and/or visual data
to the server
system 102.
[0088] In some examples, the signal receiver 310 receives communications
from the
portable electronic device 114 via the communication network 110. In some
examples,
communications include receiving user identifiers and the location from one or
more
portable electronic device 114. In addition, the signal receiver 310 can
receive audio and
video data from a portable electronic device 114.
[0089] In some examples, the signal processing unit 312 analyzes the
received
communications (e.g., data packets) and extracts pertinent information (such
as a user
identifier, a location, and a device identifier from the sending portable
electronic device).
[0090] In some examples, a profile matching module 314 accesses the user
profile
database 230 to identifier a user profile associated with the received user
profile. The user
profile database 230 includes a plurality of user profiles. Each user profile
stores at least
user identifier for the specific user and group data 332. In some examples,
the group data
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
27
332 can comprise a list of user identifiers, each user identifier is a 32 byte
value
representing a particular low energy electronic device 120 and the user
associated with that
device. The list of user identifiers in a particular user profile in group
data 332 can
represent the users connected to the user associated with the particular user
profile.
[0091] In some examples, a user can connect his or her user profile with
those of
their friends and family or others, as needed or desired. In addition, a user
can determine
the level of connection with each other member. The level of connection can
determine
which information is sent to the user when the low energy electronic device of
the user is
activated. For example, the server system 102 may receive recorded visual and
audio data
from a portable electronic device 114 associated with the user. The server
system 102 can
only send the recorded visual and audio data to users who have a sufficient
level of
connection or are otherwise designated to receive such data from the user. In
addition, the
user can designate one or more other users as a key connected user. In some
examples, the
server system 102 will initiate one of an audio call, a video call, a
livestreaming conference,
or similar live communication event with the key connected user upon receiving
the user
identifier of a user with a selected key connected user.
[0092] When the server system 102 receives location data from more than
one
portable electronic device 114, the location estimation module 114 can use the
location of
one or more the portable electronic devices 114 to estimate the current
location of the low
energy electronic device 120.
[0093] In some examples, the group manager 316 accesses the group data 332
to
identify one or more users in a group with the user associated with the user
identifier. If the
portable electronic device 114 is paired with the low energy electronic
device, the media
transmission module 322 transmits audio and visual data to portable electronic
devices of
the users in the group data 332. As noted above, in some examples, only
members that
have been specifically selected by the user will receive the recorded video
and audio data.
In some examples, the message module 324 transmits an estimated location to
one or more
users in the list of group data 332.
[0094] FIG. 4 is a diagram illustrating a system for transmitting
information from a
low energy electronic device through a portable electronic device and a server
system to a
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
28
plurality of portable electronic devices associated with a group of users, in
accordance with
some example embodiments. In some examples, a low energy electronic device 120
communicates with a portable electronic device 114. Initially, upon receiving
user input,
the low energy electronic device 120 transmits a generic wake-up signal
comprising a
generic wake-up signal 150 to the portable electronic device 114. As noted
above, the low
energy electronic device 120 uses a one-way transmission protocol to broadcast
the generic
wake-up signal 150.
[0095] In response, the portable electronic device 120 activates an
associated
application in response to the generic wake-up signal 150. In some examples,
after a period
of time, the low energy electronic device 102 stops broadcasting the generic
wake-up signal
150 and begins broadcasting a user identifier signal 152. In some examples,
the user
identifier within the user identifier signal 152 is associated with a
particular user and a
particular portable electronic device 120.
[0096] It should be noted that the communications from the low energy
electronic
device 120 (generic wake-up signal, user identifier signal, location
information, and any
recorded visual and audio data) can be encrypted, both between the low energy
electronic
device 102 and the portable electronic device and between the portable
electronic device
114 and the server system 102. In some examples, the encryption key may be
created based
on the MAC address of the low energy electronic device 120 or the portable
electronic
device 114. The encryption can be performed using any appropriate encryption
algorithm
(e.g., symmetrical encryption algorithms, asymmetrical encryption algorithms,
and so on).
In addition, the specific algorithm can be changed as needed to ensure secure
communication. Any keys can also be changed as needed.
[0097] After transmitting the user identifier signal 152, the low energy
electronic
device 120 switches into a two way communication mode (e.g., a Bluetooth
communication
protocol). While in the two-way communication mode, the low energy electronic
device
120 can receive communications from a portable electronic device 114. For
example, the
low energy electronic device 120 receives a confirmation signal 158 from the
portable
electronic device 120 that the user identifier signal 152 has been received.
As discussed
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
29
above with respect to FIG. 2 a confirmation signal 158 can cause a low energy
electronic
device to switch into "sleep mode" or other dormant state.
[0098] In some examples, the portable electronic device 114 transmits the
user
identifier signal 152 and a location associated with the portable electronic
device114 to a
server system 102. In some examples, the portable electronic device 114 may
not have
access to a computer network (e.g., a cell phone may be out of cell tower
range). In this
case, the portable electronic device 114 can store the relevant data (e.g.,
user identifier,
location, and, potentially, recorded visual and audio data) and then transmit
it when a
network becomes available. This situation may occur during a flight (when no
internet
connection is available), wherein the portable electronic device 114 can
transmit
accumulated location and other data when an internet connection again becomes
available.
The set of locations will represent the path the user took on his or her
flight.
[0099] In some examples, the server system 102 includes a group manager
316 that
uses the user identifier signal 152 to identify a user group. In some
examples, the user
group is stored in a user profile database (e.g., database 330 in FIG. 3). The
user profile for
a respective user can include a user group field for that respective user. The
user group
field for the respective user can include a list of user identifiers, each
user identifier
associated with a user connected to the respective user.
[00100] In some examples, the group manager 316 determines, for each
respective
user identifier in the list of user identifiers, a device identifier
associated with the respective
user identifier. A device identifier for a respective user identifier
represents the portable
electronic device paired the respective user. The server system 102 can use
the identified
device identifiers to transmit data to an electronic device associated with
the device
identifier. In this way the group manager 316 sends data to each of the
identified one or
more users via the paired devices listed in their respective user profiles
(e.g., see portable
electronic devices 430A ¨ 430E.)
[00101] The data transmitted by the server system 102 can vary based on the
data
received from the portable electronic device. For example, if the portable
electronic device
114 transmits recorded or streamed visual and audio data to server system 102,
the server
system 102 can relay this data to the electronic devices associated with each
user in the
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
group of identified user 440A-440E. However, if the server system 102 receives
no such
data (e.g., because the sending portable electronic device was not paired with
the low
energy electronic device it received the user identifier of) then the server
system 102 will
only transmit the location of the portable electronic device 114 or estimated
location of the
low energy electronic device.
[00102] FIG. 5 is a flow diagram illustrating a process to enable
communication
between a low energy electronic device and one or more receiving devices, in
accordance
with some example embodiments. As will be recognized by those skilled in the
art, the
present technology is not limited to a personal or portable low energy
electronic device
(e.g., one that is carried), such as the above-discussed panic button carried
by a user for use
in emergency or other distressful situations. Indeed, in some examples, a low
energy
electronic device can be configured to be included in one of several possible
locations, such
as onboard a vehicle 502 or an inventory pallet 504. Initially, and without
explicit user
input or request, the low energy electronic device transmits a generic wake-up
signal 506.
This generic wake-up signal 506 can be received by any proximate or nearby
portable
electronic devices within range of the low energy electronic device, for
example, by
portable electronic device 516. If the portable electronic device 516 has the
application
associated with the low energy electronic device installed, the application
will be activated
and the portable electronic device 516 can communicate information to the
sever system
102.
[00103] After a first time period, the low energy electronic device can
begin
transmitting identifying information 508 to the portable electronic device 516
associated
with the object or product to which the low energy electronic device 120 is
associated with.
For example, in the case of the vehicle 502, the onboard low energy electronic
device can
transmit a vehicle identification number to the portable electronic device
516. Similarly, in
the case of the inventory pallet 504, the low energy electronic device can
transmit an
inventory tracking number to the portable electronic device 516 depending on
the specific
object being tracked.
[00104] In some examples, the portable electronic device 516 forwards the
identifying information 508 to the server system 102 along with the current
location of the
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
31
portable electronic device 516 in a similar manner as discussed above. The
location
tracking engine 520 updates the current location of the low energy electronic
device based
on the received location and the identifying information 508 (e.g., the
VIN/Inventory
Tracking Number). In this way, the location of objects can be tracked at
significantly lower
costs as compared to a traditional Bluetooth device or other near-field
communication
device. Specifically, Bluetooth low energy devices are inexpensive to
manufacture and use
very little energy. So much so that a low energy electronic device may last up
to 4 or 5
years without needing a new battery.
[00105] In some examples, the portable electronic device 516 transmits a
confirmation and shut down prompt 510 to the low energy electronic device. A
confirmation prompt 510 is a signal send from the portable electronic device
to a low
energy electronic device 120 acknowledging that the broadcasted signals have
been
received. In some examples, the confirmation response further includes a shut-
down prompt
510. A shut down prompt 510 is an instruction to the low energy electronic
device 120 to
return to a dormant or sleep mode. As noted above, quickly returning to a
sleep mode
allows the amount of power consumed to be significantly reduced over time. In
response,
the low energy electronic device goes into a non-transmitting mode for a
period of time. In
this way, the low energy electronic device reduces the overall amount of
energy used.
After a pre-determined time, the low energy electronic device 120 starts the
cycle again,
allowing continuous monitoring of the location of an object or person.
[00106] In some examples, a car with a low energy electronic device can be
stolen.
The server system can receive that VIN number Identification from one or more
devices
with the associated application installed. Once the server system determines
the car has
been stolen, it can issue a lock command. A portable electronic device or
other device can
the relay the command to the stolen care and cause the stolen car to lock
immediately,
enabling the car to be recovered with minimal delay or danger.
[00107] FIG. 6A is a diagram illustrating a low energy electronic device
120
attempting communication with a plurality of portable electronic device 602A ¨
602G, with
the low energy electronic device 120 actually communicating with portable
electronic
devices 60aA ¨ 602D within a given range, in accordance with some example
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
32
embodiments. In this example, the low energy electronic device 120 is
activated and begins
broadcasting a generic wake-up signal. As discussed above in Figures 1 and 2,
the low
energy electronic device 120 transmits a 16 byte generic device identifier and
a 32 byte
generic wake-up identifier as part of a generic wake-up signal. Any portable
electronic
device with the associated application installed can activate the application
in response to
receiving the generic wake-up signal. However, the range at which the low
energy
electronic device 120 can broadcast is limited. In this example, the maximum
range of the
broadcast is represented by dotted circle. In some examples, the maximum range
of a low
energy electronic device can be 70-100 meters, but this is not intended to be
limiting in any
way. Depending on power use preferences of the user, the low energy electronic
device
120 can reduce the amount of power used by transceiver, thus reducing the
effective range
of the generic wake-up signal.
[00108] All the portable electronic devices within the effective range
(602A ¨ 602D)
can receive the generic wake-up signal. In response, the devices (602A ¨ 602D)
that
receive the generic wake-up signal activate their respective application.
1001091 As noted above, each respective portable electronic device 602A ¨
602D that
receives the generic wake-up signal will transmit a user identifier received
from the low
energy electronic device to a server system along with the location and device
identifier of
the respective portable electronic device. In this example, some of the
portable electronic
devices (e.g., 602E - 602G) are outside the effective range, and thus do not
receive the
generic wake-up signal and thus do not wake-up in any way in response to the
transmitted
signal, nor do they transmit any signal or information to the server system.
[00110] FIG. 6B is a diagram illustrating a server system method for
estimating the
location of a low energy electronic device based on the locations of portable
electronic
devices 604A to 604D that transmit the user identifier to the server system,
in accordance
with some example embodiments.
[00111] In this example, the server system receives a location and a user
identifier
from three portable electronic devices 604A to 604C. In accordance with a
determination
that none of them are associated with the low energy electronic device (none
of the device
identifiers from the portable electronic devices 604A, 604B, or 604C are
paired with the
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
33
user identifier of the low energy electronic device), the server system
estimates a likely
location of the low energy electronic device. This estimation can be made
using the
location of each portable electronic device that has received the user
identifier and
transmitted it to the server system (e.g., system 102 in FIG. 1).
[00112] If only one portable electronic device transmits the user
identifier to the
server system, the server system can use the location of that portable
electronic device as an
estimate location. In other example embodiments, two or more portable
electronic devices
transmit a user identifier and a location to the server. In this example, the
server system can
use an average of their position as the estimated location.
[00113] In the current example, a low energy electronic device has
transmitted a
wake-up identifier signal and then a user identifier signal in an area with
four portable
electronic devices (604A to 604D). The location of the low energy electronic
device is not
shown because the server system doesn't not know it. During a first time
interval, the
server system receives the user identifier from three of the portable
electronic devices,
604A, 604B, and 604C.
1001141 As pictured, the server system can use the estimated range within
which the
portable electronic devices would receive the signal of the low energy
electronic device and
determine at least one position that would allow a low energy electronic
device to reach all
three portable electronic devices 604A ¨ 604C. In this example, during the
first time
interval, the server system estimates that the low energy electronic device is
at location 610
because only in that location could all three portable electronic devices
receive the signal.
[00115] After the server system generates a first estimate for the location
of the low
energy electronic device, the server system can receive a second set of user
identifiers
during a second time interval. The second set of signals comes from a
different set of
portable electronic devices (604A, 604C, and 604D). The server system can
again use the
positions of the portable electronic devices and the range of the low energy
electronic
device to identify one or more locations at which the low energy electronic
device 120
could transmit to the devices that report the user identifier. In this second
time interval, the
low energy electronic device 120 appears to have moved, since portable
electronic device
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
34
604B is no longer receiving signals or transmitting the user identifier,
whereas portable
electronic device 604D has begun to transmit the user identifier.
[00116] With the new set of portable electronic device locations, the
server system
identifies a new estimated location 612 as the estimated location of the low
energy
electronic device. Using this updated estimated location, as well as
additional updated
estimated locations, the server system can potentially track the movement of
the low energy
electronic device. This is especially useful if the low energy electronic
device is attached to
a vehicle or other frequently moving object. As the vehicle or user moves,
different devices
can report receiving the user identifier signal. Once a pattern of movement is
determined,
the server system can estimate future movement In other example embodiments,
the
portable electronic devices can use an internal accelerometer to estimate
movement, only
turning on a GPS device occasionally to correct any wrong guesses. This allows
the
portable electronic devices to avoid using the GPS device, which uses more
power than the
accelerometer. It is noted that the location of the portable electronic
devices can be
obtained and transmitted through the installed application even if location
functionality is
not authorized or enabled in the settings of the portable electronic device.
[00117] It should be noted that each portable electronic device can include
a radio
and that radio could generate a received signal strength indicator (RSSI) for
the received
signal. The RSSI value of a signal can allow the portable electronic devices
to estimate a
distance between the sending low energy electronic device and the receiving
portable
electronic device. A portable electronic device can send the RSSI to the
server system and
the server system can use this signal to generate a more accurate estimate.
[00118] For example, a maximum range for a low energy electronic device may
be
100 meters. If two portable electronic devices both transmit an identifier for
the low energy
electronic device to the server system, the amount of area that is within 100
meters of each
device may be quite large. However, if the RSSI value estimates that the low
energy
electronic device is within 40 meters of the first portable electronic device
and within 30
meters of the second portable electronic device, the amount of area in which
the low energy
electronic device can be found is significantly reduced.

[00119] FIG. 7 is a flow diagram illustrating a method, in accordance with
example
embodiments, for responding to either a paired or non-paired low energy
electronic device.
Each of the operations shown in FIG. 7 may correspond to instructions stored
in a computer
memory or computer-readable storage medium. In some example embodiments, the
method
described in FIG. 7 is performed by a portable electronic device (e.g.,
devices 116A to
116C in FIG. 1). However, the method described can also be performed by any
other
suitable configuration of electronic hardware. In some examples, when a new
low energy
electronic device is purchased by a user, the user performs an initialization
procedure. To
do so, the user may access an application on a portable electronic device,
such as a
smartphone, and begin the registration. During the registration process, the
portable
electronic device receives a device registration request from a low energy
electronic device.
[00120] The portable electronic device can receive a user identifier
associated with a
low energy electronic device to be paired with the portable electronic device,
which user
identifier can be referred to as a paired user identifier. As noted above, the
paired user
identifier can comprise a 32 byte value that is unique to the low energy
electronic device
(and by extension the user). The portable electronic device stores the paired
user identifier
associated with the low energy electronic device. Once the portable electronic
device stores
the paired user identifier, the portable electronic device and the low energy
electronic
device are considered paired.
[00121] A user can choose which portable electronic device is paired with
the low
energy electronic device by choosing which portable electronic device to use
during
registration. In other example embodiments, a user can choose to pair a low
energy
electronic device with more than one portable electronic device or pair more
than one low
energy electronic device with a given portable electronic device.
[00122] In some examples, the paired user identifier is received from the
low energy
electronic device. For example, the low energy electronic device can be
manufactured with
a unique user identifier already included in memory. In other example
embodiments, the
portable electronic device receives a paired user identifier by transferring
the registration
request to the server system and receiving from the server system a generated
user identifier
for the low energy electronic device. The server system ultimately stores user
profiles
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
36
containing one or more respective user identifiers for each user and can then
ensure that no
user identifies are replicated. In some aspects, the user identifier(s) can be
stored on the
portable electronic device.
[00123] Once registration is complete, in some examples, the user can
activate their
low energy electronic device, or in other examples, the low energy device can
be
configured to automatically transmit. In response to activation of the low
energy electronic
device, such as when activated by a user (e.g., by pushing a button or other
input), the
portable electronic device receives (702), from the paired low energy
electronic device, a
generic wake-up signal having a generic wake-up identifier. The portable
electronic device
of the user is further capable of receiving a generic wake-up signal from
other low energy
electronic devices not paired with the portable electronic device, as
discussed herein.
[00124] In response to receiving the generic wake-up signal and the generic
wake-up
identifier, the portable electronic device can activate (704) an application
associated with
the generic wake-up identifier. In this context, activate can mean move from
an off or
dormant state into an active state. In some examples, the portable electronic
device can
activate the associated application in a discrete manner, such as without
otherwise causing
noticeable changes to the portable electronic device (e.g., no sounds are
produced and the
screen does not change). In this way the application can perform tasks in the
background
without interrupting or otherwise bothering the user.
[00125] The portable electronic device can be operable to receive (706) a
user
identifier from both paired and non-paired low energy electronic devices. Upon
receipt of
any user identifier from any low energy electronic device configured in
accordance with the
present technology as discussed herein, the portable electronic device can
determine (708),
based on the user identifier, whether the low energy electronic device whose
signal is being
received is paired with the portable electronic device.
[00126] In some examples, determining whether a given low energy electronic
device is paired or not includes accessing a paired user identifier stored at
the portable
electronic device. The portable electronic device can compare the paired user
identifier
with the received user identifier to determine if there is a match. In
accordance with a
determination that the paired user identifier and the received user identifier
match, the
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
37
portable electronic device determines that the low energy electronic device
and the portable
electronic device are paired, thus facilitating certain actions. If no match
exists, other or
different actions can be facilitated.
[00127] In other example embodiments, the portable electronic device
determines
whether the portable electronic device and the low energy electronic device
are paired by
transmitting the received user identifier and a device identifier for the
portable electronic
device to a server system, and then receiving from the server system a
determination
concerning whether the low energy electronic device and the portable
electronic device are
paired based on information stored in a user profile associated with the
received user
identifier.
[00128] The portable electronic device can perform (710) at least one of a
background function or a foreground function in response to the determination
of whether
the at least one low energy electronic device is paired with the portable
electronic device.
In accordance with a determination that the at least one low energy electronic
device is
paired with the portable electronic device and thus comprises a paired low
energy electronic
device the portable electronic device can be caused to perform a foreground
function, such
as activating at least one of the camera or the microphone to record at least
one of image
data or audio data, respectively.
[00129] The portable electronic device can then transmit the user
identifier, any
recorded image data and audio data, and the location of the portable
electronic device to the
server system.
[00130] In accordance with a determination that the at least one low energy
electronic device is not paired with the portable electronic device, and thus
comprises a
non-paired low energy electronic device, the non-paired portable electronic
device can be
caused to perform a background function of transmitting the user identifier
and the location
of the portable electronic device to the server system.
[00131] In some examples, the portable electronic device can receive, at
the same or
different times, a plurality of generic wake-up signals from a plurality of
low energy
electronic devices, each of the generic wakeup signals comprising the same
generic wake-
up identifier (but different user identifiers), and each of the plurality of
low energy
CA 03104241 2020-12-17
WO 2019/243856
PCT/IB2018/000823
38
electronic devices comprising one of a paired or non-paired (and thus a
matched or a non-
matched) low energy electronic device.
[00132] After transmitting the user identifier to the server system, the
portable
electronic device can transmit a non-paired confirmation signal (if the low
energy electronic
device is determined to be non-paired) to the low energy electronic device. In
some
examples, the non-paired confirmation signal causes the low energy electronic
device to
perform a first response and then switch into sleep mode. In some examples,
the first
response is a single vibration, or some other user feedback indicator.
[00133] After transmitting the user identifier to the server system, the
portable
electronic device can transmit a paired confirmation signal (e.g., if the low
energy
electronic device is determined to be paired) to the low energy electronic
device. In some
examples, the paired confirmation signal causes the second low energy
electronic device to
perform a second response and then switch into sleep mode. The second response
can be
two sequential vibrations, or some other user feedback.
[00134] FIG. 8 is a flow diagram illustrating a method, in accordance with
example
embodiments, for transmitting information (e.g., emergency information, and
other types)
from a user to a group of predetermined users. Each of the operations shown in
FIG. 8 may
correspond to instructions stored in a computer memory or computer-readable
storage
medium. In some example embodiments, the method described in FIG. 8 is
performed by a
portable electronic device (e.g., devices 116A to 116C in FIG. 1). However,
the method
described can also be performed by any other suitable configuration of
electronic hardware.
[00135] In some examples, a server system receives (802) situation data
from a
portable electronic device. Situation data may comprise, but is not limited to
a user
identifier and a location of the portable electronic device.
[00136] In some examples, the server system identifies (804), based on the
user
identifier, a group of users associated with the user identifier. In some
examples, the server
system accesses a user profile associated with the received user identifier.
The user profile
can include a list of connected users.
1001 37] In some examples, the server system determines (806) whether the
situation
data further comprises recorded image data and audio data. In this way, the
server system
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
39
does not need to determine whether the portable electronic device is paired to
a particular
low energy electronic device. Instead, the portable electronic device makes
that
determination and only sends visual and audio data if the portable electronic
device and the
transmitting low energy electronic device are paired.
[00138] In accordance with a determination that the situation data further
comprises
recorded image data and audio data, the server system sends (808) the user
identifier, a
location of the portable electronic device, and recorded audio data and visual
data to the
group of users. In this way, a user can pre-select a group of users (e.g.,
friends, family, and
so on) who will receive this data if the user activates the low energy
electronic device. For
example, if a user is a victim of a crime or attempted crime, they can
activate the low
energy electronic device and initiate a broadcast their location and
visual/audio data about
their surroundings to the group, which enables those in the group to take
appropriate steps
to aid the user.
[00139] In accordance with a determination that the situation data does not
further
comprise recorded image data and audio data, the server system sends (810) the
user
identifier and a location of the portable electronic device to the group of
users. In this way,
when a low energy electronic device connects to a portable electronic device
that it is not
paired with, the application does not use the additional resources or
bandwidth of the
device. Instead, it sends the minimum amount of useful data and allows the non-
paired
portable electronic device to return to other tasks.
[00140] In some examples, the received situation data comprises the
locations of two
or more portable electronic device, As seen above in FIG. 6A and 6B, the
server system
may generate an estimated location for a low energy electronic device based on
the range of
the low energy electronic device and the locations of the two or more portable
electronic
devices. Once a location is estimated, the server system transmits the
estimated location of
the low energy electronic device to the group of users.

CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
[00141] FIG. 9 is a block diagram illustrating components of a machine 900,
according to some example embodiments, able to read instructions from a
machine-
readable medium (e.g., a machine-readable storage medium) and perform any one
or more
of the methodologies discussed herein. Specifically, FIG. 9 shows a
diagrammatic
representation of the machine 900 in the example form of a computer system,
within which
instructions 925 (e.g., software, a program, an application, an applet, an
app, or other
executable code) for causing the machine 900 to perform any one or more of the
methodologies discussed herein can be executed. In alternative embodiments,
the machine
900 operates as a standalone device or can be coupled (e.g., networked) to
other machines.
In a networked deployment, the machine 900 can operate in the capacity of a
server
machine or a client machine in a server-client network environment, or as a
peer machine in
a peer-to-peer (or distributed) network environment. The machine 900 can
comprise, but
be not limited to, a server computer, a client computer, a PC, a tablet
computer, a laptop
computer, a netbook, a set-top box (STB), a personal digital assistant (PDA),
an
entertainment media system, a cellular telephone, a smartphone, a mobile
device, a
wearable device (e.g., a smart watch), a smart home device (e.g., a smart
appliance), other
smart devices, a web appliance, a network router, a network switch, a network
bridge, or
any machine capable of executing the instructions 925, sequentially or
otherwise, that
specify actions to be taken by the machine 900. Further, while only a single
machine 900 is
illustrated, the term "machine" shall also be taken to include a collection of
machines 900
that individually or jointly execute the instructions 925 to perform any one
or more of the
methodologies discussed herein.
[00142] The machine 900 can include processors 910, memory 930, and I/O
components 950, which can be configured to communicate with each other via a
bus 905.
In an example embodiment, the processors 910 (e.g., a CPU, a reduced
instruction set
computing (RISC) processor, a complex instruction set computing (CISC)
processor, a
graphics processing unit (GPU), a digital signal processor (DSP), an
application specific
integrated circuit (ASIC), a radio-frequency integrated circuit (RFIC),
another processor, or
any suitable combination thereof) can include, for example, a processor 915
and a processor
920, which can execute the instructions 925. The term "processor" is intended
to include
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
41
multi-core processors 910 that can comprise two or more independent processors
915, 920
(also referred to as "cores") that can execute the instructions 925
contemporaneously.
Although FIG. 9 shows multiple processors 910, the machine 900 can include a
single
processor 910 with a single core, a single processor 910 with multiple cores
(e.g., a multi-
core processor), multiple processors 910 with a single core, multiple
processors 910 with
multiple cores, or any combination thereof.
[00143] The memory 930 can include a main memory 935, a static memory 940,
and
a storage unit 945 accessible to the processors 910 via the bus 905. The
storage unit 945 can
include a machine-readable medium 947 on which are stored the instructions
925,
embodying any one or more of the methodologies or functions described herein.
The
instructions 925 can also reside, completely or at least partially, within the
main memory
935, within the static memory 940, within at least one of the processors 910
(e.g., within the
processor's cache memory), or any suitable combination thereof, during
execution thereof
by the machine 900. Accordingly, the main memory 935, the static memory 940,
and the
processors 910 can be considered machine-readable media 947.
[00144] As used herein, the term "memory" refers to a machine-readable
medium
947 able to store data temporarily or permanently and can be taken to include,
but not be
limited to, random-access memory (RAM), read-only memory (ROM), buffer memory,
flash memory, and cache memory. While the machine-readable medium 947 is
shown, in
an example embodiment, to be a single medium, the term "machine-readable
medium"
should be taken to include a single medium or multiple media (e.g., a
centralized or
distributed database, or associated caches and servers) able to store the
instructions 925.
The term "machine-readable medium" shall also be taken to include any medium,
or
combination of multiple media, that is capable of storing instructions (e.g.,
instructions 925)
for execution by a machine (e.g., machine 900), such that the instructions
925, when
executed by one or more processors of the machine 900 (e.g., processors 910),
cause the
machine 900 to perform any one or more of the methodologies described herein.
Accordingly, a "machine-readable medium" refers to a single storage apparatus
or device,
as well as "cloud-based" storage systems or storage networks that include
multiple storage
apparatus or devices. The term "machine-readable medium" shall accordingly be
taken to
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
42
include, but not be limited to, one or more data repositories in the form of a
solid-state
memory (e.g., flash memory), an optical medium, a magnetic medium, other non-
volatile
memory (e.g., erasable programmable read-only memory (EPROM)), or any suitable
combination thereof. The term "machine-readable medium" specifically excludes
non-
statutory signals per se.
[00145] The IU0 components 950 can include a wide variety of components to
receive input, provide and/or produce output, transmit information, exchange
information,
capture measurements, and so on. It will be appreciated that the I/O
components 950 can
include many other components that are not shown in FIG. 9. In various example
embodiments, the I/O components 950 can include output components 952 and/or
input
components 954. The output components 952 can include visual components (e.g.,
a
display such as a plasma display panel (PDP), a light emitting diode (LED)
display, a liquid
crystal display (LCD), a projector, or a cathode ray tube (CRT)), acoustic
components (e.g.,
speakers), haptic components (e.g., a vibratory motor), other signal

touches or touch gestures, and/or other tactile input components), audio input
components
(e.g., a microphone), and the like.
[00146] In further example embodiments, the I/0 components 950 can include
biometric components 956, motion components 958, environmental components 960,
and/or position components 962, among a wide array of other components. For
example,
the biometric components 956 can include components to detect expressions
(e.g., hand
expressions, facial expressions, vocal expressions, body gestures, or eye
tracking), measure
biosignals (e.g., blood pressure, heart rate, body temperature, perspiration,
or brain waves),
identify a person (e.g., voice identification, retinal identification, facial
identification, finger
print identification, or electroencephalogram based identification), and the
like. The motion

Position
System (GPS) receiver component), altitude sensor components (e.g., altimeters
and/or
barometers that detect air pressure from which altitude can be derived),
orientation sensor
components (e.g., magnetometers), and the like.
[00147] Communication can be implemented using a wide variety of
technologies.
The I/O components 950 can include communication components 964 operable to
couple
the machine 900 to a network 980 and/or devices 970 via a coupling 982 and a
coupling
972, respectively. For example, the communication components 964 can include a
network
interface component or another suitable device to interface with the network
980. In further
examples, the communication components 964 can include wired communication
components, wireless communication components, cellular communication
components,
near field communication (NFC) components, Bluetooth components (e.g.,
Bluetooth
Low Energy), Wi-Fi components, and other communication components to provide
communication via other modalities. The devices 970 can be another machine 900
and/or
any of a wide variety of peripheral devices (e.g., a peripheral device coupled
via a USB).
[00148] Moreover, the communication components 964 can detect identifiers
and/or
include components operable to detect identifiers. For example, the
communication
components 964 can include radio frequency identification (RFID) tag reader
components,

and so on. In addition, a variety of information can be derived via the
communication
components 964, such as location via Internet Protocol (IP) geolocation,
location via Wi-
Fi signal triangulation, location via detecting an NFC beacon signal that can
indicate a
particular location, and so forth.
TRANSMISSION MEDIUM
[00149] In various example embodiments, one or more portions of the network
980
can be an ad hoc network, an intranet, an extranet, a virtual private network
(VPN), a LAN,
a wireless LAN (WLAN), a WAN, a wireless WAN (WWAN), a MAN, the Internet, a
portion of the Internet, a portion of the public switched telephone network
(PSTN), a plain
old telephone service (POTS) network, a cellular telephone network, a wireless
network, a
Wi-Fi network, another type of network, or a combination of two or more such
networks.
For example, the network 980 or a portion of the network 980 can include a
wireless or
cellular network and the coupling 982 can be a Code Division Multiple Access
(CDMA)
connection, a Global System for Mobile communications (GSM) connection, or
another
type of cellular or wireless coupling. In this example, the coupling 982 can
implement any
of a variety of types of data transfer technology, such as Single Carrier
Radio Transmission
Technology (1xRTT), Evolution-Data Optimized (EVDO) technology, General Packet
Radio Service (GPRS) technology, Enhanced Data rates for GSM Evolution (EDGE)
technology, third Generation Partnership Project (3GPP) including 3G, fourth
generation
wireless (4G) networks, Universal Mobile Telecommunications System (UMTS),
High
Speed Packet Access (HSPA), Worldwide Interoperability for Microwave Access
(WiMAX), Long Term Evolution (LTE) standard, others defined by various
standard-
setting organizations, other long range protocols, or other data transfer
technology.
[00150] The instructions 925 can be transmitted and/or received over the
network
980 using a transmission medium via a network interface device (e.g., a
network interface
component included in the communication components 964) and utilizing any one
of a
number of well-known transfer protocols (e.g., HTTP). Similarly, the
instructions 925 can
be transmitted and/or received using a transmission medium via the coupling
972 (e.g., a
CA 03104241 2020-12-17
WO 2019/243856
PCT/1B2018/000823
peer-to-peer coupling) to the devices 970. The term "transmission medium"
shall be taken
to include any intangible medium that is capable of storing, encoding, or
carrying the
instructions 925 for execution by the machine 900, and includes digital or
analog
communications signals or other intangible media to facilitate communication
of such
software.
[00151] Furthermore, the machine-readable medium 947 is non-transitory (in
other
words, not having any transitory signals) in that it does not embody a
propagating signal.
However, labeling the machine-readable medium 947 as "non-transitory" should
not be
construed to mean that the medium is incapable of movement; the medium should
be
considered as being transportable from one physical location to another.
Additionally,
since the machine-readable medium 947 is tangible, the medium can be
considered to be a
machine-readable device.
